Project Name: Captcha (Secure Authentication)
Project Status: Active
Project Manager: Steffan Cline
Description: This is a project to replicate the system seen on many sites where the server gives you a graphic with text in it where you must type the text into the field to verfy that you are a human and not some system that is trying to automate a process. For example, many sites use this to verify that you are a human that may be registering an email address for a mailing list rather than a bot of some sort trying to do it. There are 3 versions posted for this. 1.0s uses a session to temporarily store the image and serve it later so that there is no disk I/O necessary. Then there is the first one I made, 1.0f which writes the images to a directory and then deletes them 2 minutes later after they have been served. 1.0p uses an encrypted key to handle this. I would say this is the recommended method. The session hides more of whats going on but the Lasso session manager doesnt have enough time to get around this. I recommend that you download and try them and see which works best for you.
